SYMPTOMS

When you start one of the Magic School Bus products listed above, you may receive the following error message:

Wave Error X: All wave devices that can play files in the current format are in use. Wait until a wave device is free, and then try again.

where X refers to a number, most commonly 7 or 10.

CAUSE

You have Microsoft SoundBits (or a similar sound-producing program) installed and enabled on your computer, or there is a .dll or .drv file other than Mmsystem.dll on the drivers= line in the System.ini file.

RESOLUTION

To resolve this problem, do one of the following:

Remark out the existing drivers= line located in the [boot] section of the System.ini. Do this by placing a semi-colon (;) at the beginning of the drivers= line, then add the following on a new line:
```
   drivers=mmsystem.dll
						
```
For more information about how to perform this task in Windows, see your Windows printed documentation or online Help.
Disable or remove SoundBits.

MORE INFORMATION

If Microsoft SoundBits (or a similar sound-producing program) is installed and enabled, you will either not hear any startup audio with the Magic School Bus program, or an error message may appear when you launch the program. This occurs because both SoundBits and the Magic School Bus are trying to play audio at the same time.
